White iPhone 4S Appears in AT&T Inventory?

According to Engadget, this is a screengrab of AT&T’s inventory clearly showing an “iPhone 4S” on the system.

A helpful tipster sent us this tasty morsel, from AT&T’s internal system, listing the “iPhone 4s White” beneath a handful of already familiar Apple handsets. Could it be? Is Cupertino actually planning on bringing a white version of its next iPhone out at launch? We’re afraid only time will tell.
